We applied the technology of microscience chemistry in performing the experiments of the practical curriculum of the principles of general organic chemistry including the process of filtration, simple distillation, crystallization, chromatographic separation, Lassayn Test , detection of functional groups in organic compounds, and preparation of some esters by refluxing. In addition, to the preparation of acetylene and ethylene gases using the tools of microscale chemistry. Radmaste center has provided us with modern microscale tools. The Arabic edition of the curriculum, sponsored by UNESCO, is available to us. It will be prepared in its final shape to be published in the website of the organization which is concerned with the practical curricula of green microscale technology. Ola Abu Ali, master degree student, Hanadi Medras, PhD student, and the lecturer Taghreed Alsufyani in Al Taif University have performed most of the above mentioned experiments using the Arabic edition for practical curricula sponsored by UNISCO, by the tools purchased from Radmaste center in South Africa. The experiments were performed easily and successfully in a relatively short time in comparison with the traditional laboratory. In addition, to the higher safety profile of the latter. The cost of the tools is very cheap. The practical curriculum is available free from UNESCO. The UNESCO made many of the practical curricula available free on its website in different languages in order to be published throughout the world. This is out of the principle of positive globalization of education and enforcement of common concepts between the world’s societies who are of multiple cultural and religious environments. Two workshops have been held lately in both Riyadh (the capital of the Kingdom of Saudi Arabia) and Makkah. The opinions of specialists, educational supervisors were distributed upon them after performing some experiments of the practical curriculum of the principles of organic chemistry, that was during the functions of the workshops. A summary of the results will be published, about the questionnaire to the specialists, about the possibility of application of green microscale chemistry technology within our curricula of educational and university learning.
